Cold groundwater and winter outages both work against your water heater
From October through April, the water coming into your house is cold, and on nights that average 26°F it's colder still. Your water heater has to work harder to bring it up to temperature, and that extra work falls on the heating element or the burner. Over time that strain shows up as a failing element, a burner that won't stay lit, or a tank that takes longer to recover between showers.
Power matters too. About 11% of New Jersey households were without power for 24 hours or more last year, and Union County has seen 33 winter storms and 98 damaging wind events over the past ten years. An electric water heater does nothing during an outage, and when the power comes back on, it should start heating again on its own. A gas water heater with a standing pilot keeps working through the outage, but if the pilot has gone out, it needs to be relit before you get hot water again.

A new water heater would cut about $90 a year off hot water for a typical New Jersey home.

Repair makes sense when an element, thermostat or gas valve has failed.
Replacement makes sense when the tank itself is leaking.
- Why is my water heater leaking from the bottom?
- Most often the tank itself has rusted through from the inside and is starting to fail. Water can also drip from the bottom if the drain valve is loose or if the temperature and pressure relief valve is discharging above it and running down the side. A cracked tank cannot be repaired, but a loose valve can, so a contractor needs to look before you know which one you have. If it is the tank, plan on replacing the unit rather than fixing it.
- Why won't the pilot light on my water heater stay lit?
- The most common cause is a worn thermocouple, the small sensor that sits in the pilot flame and tells the gas valve it is safe to keep the gas flowing. When it wears out it can't confirm the flame is lit, so the valve shuts the gas off and the pilot goes out. A weak thermocouple is a simple, inexpensive part to replace. Less often the trouble is a draft blowing out the flame or a dirty pilot orifice, both worth ruling out too.
- Can a tankless water heater be repaired?
- Yes, most tankless water heater problems are repairable. Common issues include a buildup of scale on the heat exchanger, a failed igniter, a clogged inlet filter, or a fault code pointing to a specific sensor. A contractor can pull the fault code and clean or replace the specific part causing it. It's rare that the whole unit needs to be replaced instead of repaired.
